Description

The objective of this technique is to identify the purpose of a link from the link and
its list item context. The list item enclosing the link provides context for an
otherwise unclear link when the link item is the nearest enclosing block-level ancestor
element. The description lets a user distinguish this link from links in the Web page
that lead to other destinations and helps the user determine whether to follow the link.
Note that simply providing the URI of the destination is generally not sufficiently
descriptive.

Note: These descriptions will be most useful to the user if the additional information
needed to understand the link precedes the link. If the additional information follows
the link, there can be confusion and difficulty for screen reader users who are
reading through the page in order (top to bottom).
